Evaluating The Effectiveness of Elements of

Integrated Marketing Communications: A Review of Research

Abstract

In recent years there has been strong interest among academics and marketing practitioners in the concept of integrated marketing communications (IMC). However, to evaluate the effectiveness of an IMC program, marketers must be able to determine how the use of the various marketing communication tools impact their customers. This paper reviews research and theorizing regarding ways of measuring the communication effects of the major IMC tools including advertising, sales promotion, the Internet and interactive media, public relations, and direct marketing. Research on the synergistic effects of various media and IMC tools is also reviewed.

Integrated Marketing Communications (IMC) has emerged as the dominant approach used by companies to plan and execute their marketing communication programs. Many marketers, as well as advertising agencies, are embracing the IMC paradigm and developing integrated campaigns that use a variety ways to communicate with their target audiences. (McArthur and Griffin 1997, Belch & Belch, 2004, Duncan 2005) The shift toward the IMC perspective has been hailed as one of the most significant changes in the history of advertising and promotion (Moriarty 1994; Reitman 1994) and as the major communications development of the last decade of the 20th century (Kitchen, Brignell, Li and Jones 2004).

The movement toward IMC is being driven by a number of factors including the evolution from mass to micromarketing; the fragmentation of consumer markets and media audiences; the increased use of sales promotions and public relations; the proliferation of new media and alternatives for reaching consumers, such as the internet and other digital and wireless devices; and the rapid growth and development of database marketing. New technologies such as personal video recorders (PVRs) are threatening the traditional advertising model for television and leading marketers to turn to nontraditional media such as event sponsorships, product placements, and various forms of “advertainment” such as short films shown on the Internet (Bianco 2004). As marketers work to find the right way to send the right message to the right person at the right time they are looking beyond advertising and the traditional mass media-focused approach to marketing communication.

From an academic perspective, it has been argued that IMC is the foundation of new customer-focused marketing efforts for acquiring, retaining, and growing relationships with customers and other stakeholders (Duncan and Moriarty, 1998). However, despite the growing popularity of IMC, theory development and research in this area is still limited. In fact, some scholars have argued that been critical of IMC labeling it as a management fashion that lacks definition, formal theory construction and research and is transient in its influence. (Cornelissen and Lock, 2000). However, recently more attention has been given to theory development in IMC with the goal of better defining with it is, what it does and how it can be used to guide the development and implementation of marketing communication programs (Gould 2004; Kitchen, Brignell Li and Jones 2004).

Several models and conceptualizations of IMC have been developed (Schultz, Tannenbaum and Lauterborn 1993; Duncan and Caywood 1995; Duncan 2002). However, most of the extant literature on IMC deals with topics such as discussions and debates over its definition, advantages, acceptance and measurement (Swain 2004). Empirical studies of IMC deal primarily with issues such as the extent to which companies have put it into practice, responsibility and leadership for IMC, and barriers to its implementation (Swain 2004; Kim, Han and Schultz 2004; Kitchen and Schultz 1999). However, less attention has been to one of the major problems and challenges facing IMC, which is the issue of measuring its effectiveness.

The Problem of IMC Measurement

One of the major criticisms of IMC involves the problem of measuring its effectiveness. Schultz and Kitchen (2000) acknowledged this problem by stating that “We can’t measure IMC now and it may be some time before we can.... The problem is that many marketing activities can’t be measured and the value of communication effects and impacts are even more tenuous.” The authors go on to note that: “for the most part, marketing and communication measurement suffers from an attempt to measure “outputs,” that is, what is sent out, not “outcomes” or what impact the marketing communication had.” (p.19) The measurement problem is compounded by the fact that IMC programs consist of a variety of communication tools and measuring the interactive effects of all of these elements has proven to be extremely difficult.

The measurement of the effects of IMC has not been ignored as attention has been given to the problem, with various approaches to providing metrics having been put forth. Much of the theorizing regarding the measurement of IMC comes from work done by Schultz and his colleagues. Schultz, Tannenbaum and Latuerborn (1993) note that “the IMC goal is to develop communication programs that either reinforce the present purchasing behavior of customers or attempt to influence a change in the behavior of prospects in the future.” (p. 108). They argue that behavior, in IMC terms, is any measurable activity by the customer or prospect that either moves the person closer to a purchase decision or reinforces a favorable existing buying pattern. Schultz, et. al, note that the measurement process for IMC should attempt to measure behavior that is as close to actual purchase behavior as possible, and suggest that measurement points should be built into the planning process. However, as previously noted, Shultz and his colleagues themselves have been critical of the process used to measure the effects of marketing communication due to its focus on outputs rather than outcomes.

To address the measurement problem, Schultz et. al (1993) and Kitchen and Schultz (1999) have advocated the use of an outside-in planning approach whereby the process begins with the customer and works back through the purchase decision process to determine the points at which customers and/or prospects might have contact with a brand or company. This audience perspective approach requires that attention be focused on the consumer and various contact points or opportunities for delivering messages to them throughout the purchase process, and how the impact of these contacts might be measured. Current or prospective customers can be reached through a variety of IMC tools including media advertising, sales promotion, the Internet and other interactive media, publicity/public relations, direct marketing, personal selling and event sponsorships as well as through a variety of nontraditional media. However, to effectively use these tools in an integrated manner, more work is need to determine if and how these points of contact are experienced by recipients over time, and the impact they have both individually and in combination.

A significant challenge facing IMC is the determination of ways of evaluating the effectiveness or outcomes of integrated campaigns. Marketers use IMC tools to achieve a variety of objectives including creating awareness of the company or brand; to make consumers familiar with attributes, features and benefits; to create, maintain and/or change brand attitudes, preference and purchase intentions and ultimately to influence brand choice in the form of purchase behavior. Perhaps the most important aspect of developing effective IMC programs involves understanding the responseprocess consumers go through in moving toward a specific behavior (such as the purchase of a product or service) and how the various communication tools can be used to influence this process. Marketers are interested in relevant intervening variables that are can be used as measures of movement through this response process and as outcomes of the contact they have with the company or brand. Response metrics such as those listed above are routinely measured by marketers and considered to be important outcomes of IMC effectiveness.

To better understand how to measure the effectiveness of IMC, attention needs to be given to what is known about how the various communication elements influence the response process of consumers. The purpose of this paper will be to review extant theorizing as well as research that has been conducted regarding the effects of traditional IMC tools such as advertising, sales promotion, the Internet and interactive media, public relations/publicity and direct marketing on the response process. Consideration will also be given to how the various IMC tools might interact and their synergistic impact. The goal is to provide insight and understanding of how the various IMC tools serve as contact points that affect consumers at various levels and how knowledge of their impact and effectiveness can be used in the planning, implementation and evaluation of IMC programs.

Advertising Effects

The IMC tool that has received the most attention and theorizing regarding its impact on the response process of consumers is that of advertising. Much of the theorizing regarding advertising effects deals with consumers’ processing of advertising messages. The focus of this work is on more immediate responses to advertising as a form of persuasive communication and includes the cognitive response model of persuasion (Greenwald 1968; Wright 1980) as well as the relevance accessibility model (Baker and Lutz 1988, 2000) and the elaboration likelihood model (Petty, Cacioppo and Schumann, 1983). Excellent reviews of these models and theories are provided by MacInnis and Jaworski (1989), Meyers-Levy and Malaviy (1999), and Vakratsas and Ambler (1999).

Of more relevance here, however, is theorizing regarding the effects of advertising over time rather than immediate responses to persuasive advertising messages. The dominant conceptualization of how advertising works from an intermediate to long-term perspective is through some type of response hierarchy model (Strong 1925; Lavidge and Steiner 1961; McGuire 1978; Vaughn, 1980). As noted by Weilbacher (2001), hierarchy-of-effects (HOE) models have been around in the literature of marketing in one form or another for more than 100 years.

There are several conceptualizations of HOE models which have received a great deal of attention among practitioners as well as academicians. The first is the response model proposed by Russell Colley (1961) as part of his work for the Association of National Advertisers, which resulted in the book Defining Advertising Goals for Measuring Advertising Results. Colley’s work became known by its acronym (DAGMAR) which presented an approach to setting and measuring advertising goals and objectives based on a hierarchical model of response with four stages: awarenesscomprehensionconviction and action. The DAGMAR text was revised by Dukta (1995), however, the basic hierarchical response model was retained as the basis of the DAGMAR approach.

Perhaps the best known of the response hierarchy models is that developed by Lavidge and Steiner (1961) as a paradigm for setting and measuring advertising objectives. Their hierarchy-of-effects model depicts the process by which advertising works by assuming that a consumer passes through a series of steps in sequential order which include: awareness knowledgelikingpreferenceconvictionpurchase. A basic premise of this model is that communication effects from advertising occur over a period of time. Advertising generally does not lead to immediate behavioral response or purchase, but rather a series of effects must occur, with each step fulfilled before the consumer moves to the next step in the hierarchy.

Another type of hierarchical response approach to advertising is the information processing model of advertising effects developed by McGuire (1968). This model assumes the receiver in a persuasive communication situation is an information processor and problem solver. The stages of this model are similar to those in other HOE models and include presentation  attentioncomprehensionyieldingretention behavior. McGuire’s model includes a stage not found in the other models, which is retention - or the receiver’s ability to retain that portion of the comprehended information that he or she accepts as valid or relevant. This stage is considered important since most advertising campaigns are designed not to motivate consumers to take immediate action, but rather to provide information they will use later when making a purchase decision.

McGuire’s model views each stage of the response hierarchy as a dependent variable that should be attained and that may serve as an objective of the advertising communications process. He also notes that each stage can be measured and thus provide the advertiser with feedback regarding the effectiveness of various advertising strategies. For example, exposure/presentation can be measured with figures on audience size (television or radio ratings, magazine or newspaper circulation figures), attention, comprehension and/or retention can be assessed via recall or recognition tests, while acceptance or yielding can be measured through attitude and intention measures.

Both the Lavidge and Steiner and McGuire response hierarchy models imply that either consciously or subconsciously, advertising has some intermediate effect before it impacts behavior. The two major types of intermediate effects are cognition, the thinking dimension of a consumers’ response, and affect or the feeling dimension. Cognitive effects include outcomes such as awareness, knowledge, comprehension and retention. The affective dimension includes measures such as feelings, attitudes, preferences, desires, and intentions.

However, Vakratsas and Ambler (1999), and Ambler and Goldstein (2003) argue that experience is a third principal intermediate effect that must be considered when studying the impact of advertising. They note that behavior feeds back to experience as product preferences are often formed after an initial trial. In some situations, product experience may be the dominant factor that impacts beliefs, attitudes and preferences, and the role of advertising is to reinforce existing habits, frame the experiences or serve more of a reminding or reinforcing role.

While the advertising response hierarchy models are considered of value in establishing communications objectives, a number of researchers have noted that there are problems with HOE models. Major criticisms of these models include their reliance on the concept of a linear, hierarchical response process (Huey 1999; Moriarty 1983; Preston 1982), and that the models are poor predictors of actual behavior (Bendizlen 1993). Vakratsas and Ambler (1999) reviewed more than 250 journal articles and books in an effort to better understand how advertising affects the consumer. They concluded that cognition, affect and experience are the three key intermediate measures of advertising effects. However they argue that there is little support for the concept of a hierarchy or temporal sequence of effects and suggest that they be studied in a three dimensional space rather as a hierarchy.

Huey (1999) argues that advertising effects are part of a continuous process rather than a series of steps toward an end game of purchase or adoption. He notes that advertising plays a continuous role in the process of persuading consumers and proposed a double helix model that includes message, media and time and the time span over which interactions between these two variables occur. Still others, (Cramphorn, 2004; Eichenbaum and Bodkin, 2000; Gordon and Ford-Hutchinson, 2002; Hall, 2004), believe that affect may actually precede cognition, and/or that it is intrinsically interwoven with how we think about advertising. Young (2004) further concluded that affect may correlate positively with some cognitive measures such as attention and purchase intention, and negatively with others such as recall. He concludes that “affect has a role to play in terms of short term sales effects and long term brand building efforts” (p.233).

Weilbacher (2001, 2002) also has been critical of hierarchy models arguing that they do not provide an accurate description of the effects of advertising, and that they have never been explicitly validated. Weilbacher, as well as Vakratas and Ambler (1999), argue that the hierarchical temporal sequence on which these models are based cannot be empirically supported and that they are intuitive, but nonvalidated explanation of how advertising works.

While a number of concerns and issues regarding HOE models of advertising effects have been noted, others have defended their value to advertising practice and research (Barry and Howard 1990; Barry 2002). Barry (2002) contends that HOE models remain important to both the practitioner and academic community and notes that the framework is appealing because it simple, intuitive and logical. He argues that HOE models do help predict behavior despite the imperfection of these predictions; they provide information on where advertising strategies should focus (cognition, affect or conation) based on audience or segmentation experiences; and they provide good planning, training and conceptual tools. He calls for practitioners and academic collaboration to better understand how advertising works, testing of alternative temporal sequences of the hierarchy model, and ascertainment of the value of information from research derived in this area for advertising management.
